MILKING-MACHINE.

Specication of Letters Patent. Patented Dec, 1 3, 1910, 4Appimnnm inea April 1e,

To all 'whom 'itmay concern: v

Be it known that I, J'ENS NIELSEN, subject of the King of Denmark, and residingin Copenhagen, Denmark, have invented certain new and useful Improvements in Milkineltlachines; and I do hereby 'declare the fol owing to be a full, clear, and exact description of the invention. This invention relates to milking-machines and more particularly to that kind of machines described in al U. S. Patent granted to me and bearing the No. 917,888. In these machines :the milk is pressed out of tlie teats of the cowrby means of-shields applied to the teats andfuponl which va pressure 1S exerted. l

An object of the invention is to provide a milking-machine in which 'milking members are actuated by means of flexible elements so that the operation of the machine may be performed from a distance.

Another object of the invention is to actuate the milking members alternately toward each other and away from each other, so as to imitate theaction of hand milking.

`\nother object of the invention is to ar range the milking members in pairs and tov actuate alternatingly pairs of the milking members h v lifting and lowering the same and hy snmltaneouslj' pressing the same against each" other and removing the same from each other lo more closely yimitate hand milking.

Other objects will be more fully under-` stood by referring to the following specification in connection with the accompanying drawings and theywill be more fully pointedout 1n an'dl'xy the appended claii'ns.

The drawings show by way of example an emlnuliment ot' this invention and it will be umlerstoodthat the invention is not limited to the specific combination and arrangement of parts shown in the drawing.

Figure 1 is a side ele yation of a frame in which the. milking members are mounted. Fig. is a section through the sameon a horizontal line. Fig. 2? is a rear elevation of a milking member. Fig. 4 is a side elevation of the actuated mechanism. Fig. 5 is a front elevation of the same. Fig. 6 a section similar to Fig. 2, taken through the modilied frame. Fig. 7 shows in frontI elevation the means for suspending the device on the animal to be milkcd. Fig. 8 is a side ele\'a tion of the same. i

. The milking-machine comprises a frame f1 `ment 32 which extends through the projec- 1910. Serial'No. 555,783.l

preferably made of sheet iron or some other suitable metal and having the form of a' hoop. The frame serves as a supporting device for pivots 5, 6, 7, and 8 from which the arms 9 and 10, 11 and 12, 13 and 14, 15 and 16 extend respectively. The arms are rotatably mounted at one end in these pivots vand their other endis' fastened to the milking'members. The milking members 17,18, .19 and 20 are arranged Iin coacting pairs' 17-18 and 19-20 respectively. The embodiment shows' the milking members having the form of slightly curved shields which are movably Suspended on'the arms extend ing from the frame of the machine. The member 17 is fastened to the arm 9 by means of the pivotal rod 21 and to'the arm 16 by means of the pivot 22. In a similar way the member 18 is fastened to the arm 10 and 15 75 by means of the pivot 223 and 24 respectively The other pairof milking members 19, 20

fastened to the arms 11, 13, and 14, 12 respectively, and the pivots 25 and 26 serve asl connecting means between the arm 11 and the member' 19 and between the arm 13 andthe member 19 respectively, while the milking member 20 is connectedto the arms 12 and14 by means of the pivots 2T and 28. The rod 29 shown in pivotal connection with '85 'the milking member 18 and extending above the membersl 19 and 2O serves as one of the means for actuating the same. The front end of the rod is provided with a projecting portion 30 against which a flexible element 90 31 is resting, said element having the form of a tube or hose and being non-compressible in longitudinal direction. This tubular element 31 surrounds another flexible eletion 32 and which is fastened to the upper portion of the milking member 19. This element 32 also is flexible but it is not extensiblexijn longitudinal direction.

A rod B3 is in pivotal connection with the lower end of the milking member 1S andit is, similar to rod 29, at its front end provided with a projection extending upwardly. A\ flexible but not compressible element 34v abuts against the projection o li the lower rod E05 32? and incloses a flexible but not extensible.,` element I l which is continued through the projection of the rod 31% which is fastened to the lower portion of themilkii'iginember 19. Two helical springs 36 disposed preferably in a plane 'lla llel to the frame are fastened to lugs'? dependingfrom Said .frame and at their other end they are secured to the center .portion of the milking' member 19.l Pins 38 are fastened to the lmember '1,9 and serve as a mounting means forth'e springs 36. 'In a similar way one milking member of the other pair is in resilient connection with the opposite side of the frame 4. For this purpose 2helical springs i lug 40 depending from the frame 4.

ByA reference to Fig. 3 in which the springs 36 are shown' diagrammatically in the form of, circles, it will be seen that the rod on the .milking member 18 which serves for supporting the 4 spring 39 is provided with odset portions to permit the passage of the springs 36. It .is obvious that these resilient meinbers 36 and '39 respectively are adapted to 'return the shields 18 and 19 into the starting ,position after the same have been moved toward .their companion members 20 and 17 respectively. .Each of the milking members 18 and 19 lis resiliently connected with the companion member of the other pair. Thus the member 18 is in connection with 1 the member'20 while the member 19 is resiliently connected with the member 17.

As resilient connecting means between the memberlS and the member 20, 4 springs are arranged in pairs, two of said springs connecting the upper portions of the shield 18 with theV upper portions ofthe shield 20 while 2 springs 43also serve for connecting the lower portions of these shields. In a similar way the member 19 is connected by means of 4 spri s 41 to the member 17. By reference to Fig. 3 it will'also be noted thatthe rods which serve for fastening the springs 43 to the milking member 18 are providedwith offset portions near their ends, so as to permit the passage of thesprings 41 therethrough. 4 In Fig. 2 the position of the teats with respect to the frame ,is ingilicated by dot-ted circles 44 and 45. I

I n. the modification shown in Fig.x 6 a resilientframe 101. is disppsed about lthe milking shields 19 ,and 20, said frame being fastened to said shields fand being laterally secured to the frame 4 by means ofthe rivet pins 6- and 7. The resiliency -of the frame is adapted' tohold the two milking.

members apart from each other and one of the members is connected with the actuating element 32 by means of a helical spring A102.

The other' pair of milking members 17 and 18 may .bejai'ranged in a way shown and described'with reference to theFigs. 1, 2,

and 3 or t-he same may also beprovided with a frame similar to the frame 101.

The actuating elements 31, 34 .and 35 are led to the driving mechanism shown in Figs. 4 and 5. The tubular members 3 1 and 7 34 are fastened to a movably suspendel socket 45, while the members 32 and 35 extend'through the socket and are fastened to two oscillating arms'49 and 49a. The socket 45 is' at its upper end provided with a plate 46 which serves as a closing means for the socket and fromwhich extend 2 lugs 47.-

l' The lugs areprovided with apertures and serve as ears for the shaft 48 extending therethrough. The shaft 48 is suspended in frames 56 and 57 which are fastened to the base plate 55 of the mechanism and are provided withfbearings 59 for the .shaft 48. The 2 levers 49 and'49a oscillate about the shaft 48 andone arm of the same is provided with a roller. The other arm is provided with means for fastening the element y 32 and 35. respectively to the same. The bell crank .lever51 is mounted movably in the lug 52 extending .from the rear of the socket 45. One arm of the lever 51 projecting substantially in horizontal .direction carries at its frontend a hook while the other arm of said lever 53 extends downwardly -and the spring 54 is interposed between the-last named arm 53 and the socket 45 and by means of said lspring the other arm 5l is pressed upwardly so as to enter mounted on the base plate 55. The brackets 56 and 57 serve'as bearings for lthe main shaft 58 which may be driven by some suitable means, not shown. Two cam disks 100 .into engagement with a screw 60, adjustably and 100 are mounted on saidshaft and in the rotation of the same they engage the roller 50 at the end of the arms 49 and 491 respectively, imparting thereby the oscillatory movement to said arnis and to the socket 45 which in the same Way as the armsI 49,l is fastened to the shaft 48. It will be seen that by this mechanism as described and shown,a pull is exerted upon the 'flexible element 32 and 35. respectively. By suitable adjiistmento'fthe cam diskj100 and 100, the movement of these elements may take place alternately so that the milkinv members also are alternately moved to an fro. The screw60 may be adjusted so that the same is adapted to hold the socket 45 'verse members 78 and 7.) on the side of the` animal, a transverse member 80 on the highest pointvof the back. The last named transverse member 80 carries an upright ,for

cords 81 and 82 are preferably inclosed in' on the loop 98 both of the strings Sland 82 cured to the body ofthe animal by means of nal direction upon Athe tubular elements 31- tively. 'It is obvious that rota-tion of these tubular members or channels is impossible strings 81 sind 82 are not directly connected `fore possible that the milking device is lowstrings 81 and 82 are guided over the 'pulleys 98 and 94 rotatably mounted on the upvright which is attached to the transverse wana fastenin thereto` the cords 8l and 82 respective y which below the body of the animal end in hooks 83 and 84. I

The milking apparatus as described above is preferably connected to these hooks. The

curved ieces 85 and 86 which are rotatably d on :thev transversemember 78 and 79, by mean's of pivots 87 and 88 respecas long as the .cord extending therethrough 1s under tens1on. I

In the embodiment shownin Fig. 7 the to the milking device, but some other tension members 89 and 9() are connected to said strings by, interposition of springs 91 and 92 between the strings 81 and 82 and the tension members 89 and 90. It is thereered or raised with respect to the body of the animal in accordance with the weight of the. receptacle into which the milk is conveyed primarily from the udder. The

niember 80. The string 81 is also guided over a pulley 103 and both 'of the strings 81 and 82 are 'united at 98. By exerting a pull are draivn 1ipwardly and the entire milking apparatusl may be raised .A wedge fastened to the front end or'y a lever 9T serves for holding the strings 81 and 82 in adjusted position by entering between the pulleys 93 and 94 and the spring 96 serves to press the wedge downwardly so that the same clamps the springs automatically against` the pulleys and holds the milking apparatus in adjusted position.

The :frame 4 is inclosed in its lower part by a receptacle 61. In Fig. 8 means are disclosed for conveying the milk from the receptacle 61 toa larger' pail 64 whicliis se-I a strap 65. A tubing 62 telescopingly'y extending' .with one end into the receptacle 61 and with its other end through the boss 63 into the pail 64se1vesfor conveying the milk from the machine into said pail.

The operation of thev device is the following: The frame 4 suspended from the animal by means of the strings 81 'and 82- which are adjusted so that the teats of the animal arel between the milking members 17, 18, y19 'and 20. 7lhe elements 31, 32, 34 and 35 aresecmed to the driving mechanism disclosed iniFigs. 4 and 5 and by rotation of the shaft 58- a `pull mayrbe effected alternately on' the cord 32 and 35 while simultaneously a pressure is exerted in longitudiand 84: If the ele-ment 32 is 'pulled by raislower portions of the members of' ing the front portion of the arm 49, the upper part of the milking members of each pair are pressed against each other, entering thereby into engagement with the base of the'teats. This action results from the mounting of thetiexible element immediately on the milking member 19 and from the mounting of the rod 29'which is connectedto the tubular member 31 on the milking member 18. The movementof the nnlkmg member 18 1s transferred to the m1lking member 2O by means ofthe springs #43 so that the milking member 2() is pressed toward t'he' left when the milking member 18 is pressed in said direction,'and the milking member'l is moved toward the right when the milking member 19 is moved in the same direction. The movement of the milking nre'mbers causes an oscillating of the pivotal arms 9, 10, 11, 12, 18, 14, 15 and 16,'vvl1ich are connected to the upper edgesof the members. By this means the milking shields 17 to 20 are raised some-,

Whatin the direction toward the base of the teats at,- the same time that they are brought in enga ement with the same. 'By means of the cor 35 and the tubular member 34, a similar movement is transferred to the lower portion of the milking members, while at,

the same time the milking members are lowered somewhat through Athe action .of the pivotal arms. f i

It will be seen that in the compression ot the milking members toward each other at th'eir lower ends, the upper portions of the same move apart from each other. The return movement of the shields is partly effected by the action of the springs 36 4and 89.
